If you experience any noticeable latency with Rocksmith, then it’s more than likely due to the specific setup you’re using. Since everyone has a unique arrangement with their home entertainment systems, we’ve outlined steps you can take to avoid this issue.

If available on your TV, use the Game or PC mode setting. These modes bypass extra video processing filters to seriously reduce lag time.
If the TV does not have a Game or PC mode, you can diminish lag by turning off video processing filters. Refer to your TV manual for more information on how to turn off processing filters.

Check to see that the console is outputting video at the native resolution of your TV. If your TV’s native resolution is 1080p but your console is set to 720p, the TV must process the signal to scale the image up to fill the entire screen, which adds to the input lag.

On some TVs, HDMI connections can introduce more input lag than component or PC cables. If your TV has noticeable input lag using HDMI connection, you can diminish the lag by switching to component video cables or PC cables.

If you’re using external speakers, connecting the audio from the console to a stereo receiver or home theater system using analog audio cables can fix audio lag. To match the on-screen note display to the audio, you can advance the notes using the Note Advance calibration.

Thanks for the suggestions but why does nobody understand that it's not the audio or video lagging. There is a latency issue with the game processing the guitar and replaying the sound. I hit my strong and 1/2 second later it comes out of my speakers.

All of these have the same issue. I have found a way to work around it but it sucks. I put my headphones on but not over my ears, that way I can hear the drums but I listen to the sound of my actual guitar, not my guitar through the game. I got platinum and gold on a bunch of songs this way.

2. HDMI to TV (LG 40") and RCA stereo from universal component cables plugged into headphones (Turtle Beach wired). Component cables can't be official MS cables because they block off the HDMI output slot (because 360 doesn't handle both outputs correctly - do not switch TV inputs or turn off TV while both are plugged in or 360 will reset).

Universal gaming component cables are available at EB Games or GameStop for very little money ($10-$20). They work well.

Note Advance calibration?

Where do I find the Note Advance calibration setting? i've set the video lag setting to 0 but there is still a slight lag in the test sound/visual. My real problem is the 1/2 second delay between me plucking a note and it sounding in the game. I am using the Xbox 360 component cable with the video input (R/G/B) and analog input (L/R) both plugged into the 'Component In' input on my Sharp LCD TV. Do I "have" to push my audio directly to/through a separate receiver to eliminate the audio lag? This would make for a very expensive Rocksmith accessory if you didn't already have one.

With my current audio lag the game is unplayable.

PC Rocksmith 2014
There is a log.
The minimum and most acceptable results I can get by using headphones (with no DSP).
The lag is very noticable on TV (in PC game mode without connecting a video cable, just audio 3.5mm jack) the same happens on receiver (either analog audio input 1,2 or aux 3.5mm)

Did anybody try to use (old style) analog amplifier(with no DSP)?
What results did you get?

Whatever you use you want no DSP. I use studio monitors connected to an external interface but any setup where the signal is not processed further is what you want.

Change audio output

I was having same issue strum string and delay between sound by quite a lot. I'm using Hdmi to tv optical from ps4 to surround sound system. Go to ps4 settings select audio menu click primary audio out to optical. Unchecked everything apart from linear pcm boxes. All Change bitstream to pcm. Got rid of delay completely ad not decoding sound anymore.
Hope this helps.
